BULL ROPE. a

Application filed March 15, 1923. Serial No. 625,375.

To all whom it may concern:

Be it known that I, WALTER L. F AUS'I, a citizen of the United States,and a resident of Newark, in the county of Essex and State of NewJersey, have invent-ed a new and Improved Bull Rope, of which thefollowing is a full, clear, and exact descrip tion.

The present invention relates to new and useful lmprovements in cordageand it pertains more particularly to that type of cordage known as bullropes. Due to the use to which bull ropes areput, great strength is notrequired. It is necessary, however, in the manufacture of bull ropesthat sufficient Size or diameter be obtained.

In the manufacture of ropes generally, the product is formed of strandswhich strands in turn are composed of ya'rns and said yarns in turn arecomposed of spun fiber. In manufacturing yarns, the fiber is subjectedto various operations and machines, and at one. step or another in theseveraloperations, lubricant in the form of specific oils, is appliedto'the fiber.

In carrying out the several operations by which'the fiber is convertedinto yarns, there is considerable waste separated from the fiber mass,in the form of short fibers, organic matter not removed by the originalretting, and other foreign matter, which waste is separated from thefiber in order that the fiber may be in the most desirable condition forthe manufacture of cordage.

This Waste is known in the rope-making art as rope mill waste.

As above stated, rope mill waste consists of short fibers, acomparatively lar percentage of the above-mentioned organic matter, andconsiderable foreign matter, the whole being practically saturated bythe lubricant used in preparing the fiber for cordage operations. andthis mill waste, so far as is known, prior to'this invention, has had nocommercial value. b p

Due to the character of. this rope mill waste,- it is of a flocculentnature, and it has been found by experiment that the degree offlocculence thereof is very high. It has also been found by ex erimentthatrope mill waste ossesses a egree of compressibility especiallydesirable when usedinthis connection. It 1s, therefore, one of the pri-'mary. objects of the present invention toin any desired manner.

required to carry great loads, they are in use subjected to excessivefriction and the ollwith which the rope mill waste is practlcallysaturated, lends itself as'alubricant for the finished product when therope mill waste is used as the core of the strands or of the rope itselfin a bull rope.

As aforestated, one of the requirements of the bull rope is size, and byemploying rope mill waste as a core, due to the flocculent nature ofsaid material, it readily lends itself to cores of various diameters,thus giving. the necessary bulk.

With the above and other objects in view, reference is had to theaccompanying drawin in which igure 1 is a view in elevation of a sectionof bull rope. constructed in accordance 'Wlth the present invention, oneof the strands being partiallyunraveled;

Fig. 2 is a transverse sectional view taken on the line 22 of Fig. 1. VIn carrying out the invention, rope mill waste is formed into a coredesignated by the reference character 5 in the drawings, After this hasbeen done, the core is provided with a protecting cover in the form ofyarns 6, preferably spirally laid about 'the core, and this structure isknown in the art as a strand. After the strands have been formed of thecore 5 and yarns 6, a plurality of such strands are laid together toform the bull nope, designated by the reference character 7 in thedrawings.

From the foregoing it is apparent that. the present invention provides anew and improved rope structure, the manufacture of which permits of theuse of a heretofore waste by-product which prior to this invention waspossessed of no commercial value.

What is claimed is: 1. In a cordzfige element, a. core comprising, amass of occulent material.

- 2. A rope element comprising a core of fiocculent material, said corehaving a covering of spirally laid yarns.

3. A rope elementhaving a core formed 5 of flocculent material, saidflocculent material comprising rope mill Waste.

4. A bull rope comprising a plurality of elements inintertwined-relation, said clements having a core of a flocculcnt mass,which flocculent mass comprising ropc mill 10 waste is impregnated Witha lubricant.

5. A Cordage element having a core of flocculent material possessed of ahigh dcgrce 0f compressibility.
